To all whom it may concern.-

Be it known that I, HARRY PAULING, engineer of mines, a citizen of the Empire of Austris-Hun gary, and a resident of Brandau, Bohernia, Austria-Hungary, (whose post-oice address is House-No. 200,) have invented certain new and useful Improvements in Apparatus for Treating Gases,&c. ,of which the following is a specification.

This invention relates to an improved apparatus for the treatment of gases, vapors, and the like by electric-spark discharges.

For certain purposes-for example, the ozonizing of oxygen for converting the nitrogen of the atmosphere into nitrous acid and the likeit is necessary to expose air, gases, gas mixtures, or mixtures of gas and air, or vapors of all kinds, and the like which may contain liquids in a finely-divided condition, separately or several, simultaneously to the eiect of electricspark discharges. The method hitherto in use consisted in produc` ing the electric spark in a space or chamber filled with the particular gas or in a current of gas between two ordinary electrodes. It

will be obvious that in this case the spark could only act upon a small quantity of gas at a time, and it is impossible to subject all parte of a given volume of gas uniformly to the action of the electric spark. A

The apparatus forming the object of the present invention is based -upon a process which enables the continuous treatment of gases and the like by means of spark discharges in such a manner that every particle of the gas is compelled to come into contact with the spark. The said process consists, essentially', in the fact that by a suitable :'orm of the electrodes between which the spark is produced the sparking surface is a conical one and the gases are blown orsucked through this sparkcone. The apparatus suitable for this arrangement and forming the object of thisinvcntion is represented in Figures 1 to 4 of the annexed drawings.

Fig. 1 is a. vertical section, Fig. 2 au end view, and Fig. 3 across-section on line A. A of Fig. 1. Fig. 4 shows a'modiiication consistingofatubular electrode terininatinginacup.

The novelty of this apparatus lies in the fact that the positive electrode is of pointedA are sucked out of the cylinder a by inea-ns of shape and the negative electrode has a disk shape, whereby the discharge-sparks are conical with the base directed toward the disk and its apex at thedischarging point. The blowing in of the gases and the like to be treated is effected through this point in the direction of the spark-cone in suche manner that the greater part of the gas-current coincides with the spark-path. The outlet of the gases after the treatment is completed preferably takes place through openings in the disk electrode.

In the cylinder a the two electrodes and c are axially inserted and connected with the poles of au induction-`coil. A Theseelectrodes are tubular andsuitably insulated from the cylinder. One of the electrodes, b, terminates in a nozzle e,while the other, c, carries a cup or plate d at its end opposite the nozzle, placing the inductioncoil in circuit. The jumping of the spark takes place in the vshape of a cone with its base directed toward the edge of the cup d, the apex 'of the cone being in the nozzle e. The gais 1r gas mixture to be Vtreated is-blown thro s 'i the pipe b by means of a blower or from a gas-meter. The gases which have beensubjected to the treatment the second pipe aand passed on to be further dealt `with. The.' electrode carrying the cup d can be open toward the second electrode e by a disk or cup, being provided with a number of tine holes, as shown in Fig. 4.

In the apparatus described abcvethe. gases, gas mixtures, or vapors can be subjected to the treatment in a more or less cooled or heated state and under normal, increased', or reduced pressure. They can also be saturated with finely-divided liqn ris, such as water..

The temperature of the gasesor vapors-to be treated in this apparatus, as well as their pressure, changes according tothe nature of the gases or vapors and the nature of the products to be obtained.

Having now particularly described and ascertained the nature of my invention, I de*- clare that what -I claim isf- 1. An apparatus for treating gases and the like by means of the electric spark, comprising two electrodes arranged in line, one o them formed by a tube ending in a nozzle,

the other one ending in a disk; the whole hollow of said tube, substantial'y ashown 16 preferably inciosed in' an insulating-casing, and deseribed. 1 Y substantially as shown and described.
